Azul Systems have already made bold claims over their project,
saying it is the most scalable JVM for enterprise Java workloads,
aiming to cut operating loading times with improved capacity and
throughput. So much so that they also claim to be the only JVM to
support application in excess of 512GB of memory, yet still
simplifying Java deployments and reducing operating costs to the
business.

The main draw for Zing appears to be its ability to eliminate
common scalability concerns such as garbage collection issues and
also enable several Java applications with minimum fuss – creating
quicker response times. Azul say that it is based upon Oracle’s
HotSpot, meaning that changes are indeed minimal.

For example, for distributed caching and in-memory data
stores, Zing sustains a 5.7 times greater throughput (ops/sec)
based upon the Yahoo! Cloud Serving Benchmark and for
portals/ecommerce workloads, Zing carries 18 times more concurrent
users. Very impressive stats.

Gil Tene, CTO and co-founder at Azul Systems comments on the
significance of releasing Zing.

“For the first time companies and application developers have a
choice in JVMs for commodity platforms. Zing 5.0 overcomes
traditional Java tradeoffs improving key performance and
scalability metrics at the same time,”

Chief Analyst at 451 Research (a division of the 451 group),
John Abbott said of the release:

“The Zing JVM could help solve the scalability problems that
have held back Java for the past 15 years. It’s likely to
prove a visible and important contribution to the success of
enterprise Java deployments and mission-critical Linux-based
applications.”

100 percent Java-compatible — Zing is a
100 percent Java-compatible JVM based on the Oracle HotSpot JVM.
The Zing JVM is simple to install and requires no changes to the
application code or operating system.

Improved application availability and infrastructure
elasticity — Individual Zing instances can
automatically scale up and down both memory and CPU resources based
on real-time demands to achieve required response time and
availability metrics, even under extreme loads.

Simplified deployments and
manageability — With Zing’s unique ability to utilize
larger, more elastic JVMs, enterprises are able to reduce Java
instance counts by 90 percent for the same sustained application
throughput, response time and availability. In addition, the Zing
Vision always-on, production visibility tool allows administrators
to diagnose application problems seamlessly in production, reducing
tuning iterations and shortening development life cycles.

Zing 5.0 is available on trial here, so you can try it
out for yourself. Pricing is based on annual subscription per
